------------------------------------------------------------
[~jagsancio], do you have any update on this? Maybe we don't need the
`snapshot` cleanup policy anymore because it works fine currently for the
time/size cleanup.

[~jagsancio], do you have any update on this? I think this is important to
avoid old snapshots staying in the disk forever. Do you need help on this?

> It looks like delete policy needs to be set to either delete or compact:
> {code:java}
> .define(CleanupPolicyProp, LIST, Defaults.CleanupPolicy,
> ValidList.in(LogConfig.Compact, LogConfig.Delete), MEDIUM, CompactDoc,
> KafkaConfig.LogCleanupPolicyProp)
> {code}
> Neither is correct for KRaft topics. KIP-630 talks about adding a third
> policy called snapshot:
> {code:java}
> The __cluster_metadata topic will have snapshot as the cleanup.policy. {code}
